Reflection of a Figure

Triangle DEF reflected over the X-axis and translated three units left. What are the new coordinates for angle D?

Reflect ΔXYZ over the line y = x.

X(0 , -3) ; Y(-2 , 4) ; Z(1 , 3)

• X'(0 , 3) ; Y'(-2 , -4) ; Z'(1 , -3)

• X'(0 , -3) ; Y'(2 , -4) ; Z'(-1 , 3)

• X'(-3 , 0) ; Y'(4 , -2) ; Z'(3 , 1)

• X'(0 , -3) ; Y'(2 , 4) ; Z'(-1 , 3)
